Description

[Detailed Description of the Invention] The present invention relates to a control device for a main clutch, and more particularly, to a control device for a main clutch mounted on an engine mounted on a vehicle body via an elastic body.

Conventionally, this type of main clutch control device has been such as one in which an operating member provided on the vehicle body and an actuating member of the main clutch are linked via a cable, or via a rond using a ball joint. It has been known.

However, in the former case, the vibration of the main clutch due to engine vibration can be absorbed by the cable, but the cable stretches during use and the operating member does not operate sufficiently in response to the stroke of the operating member (pedal), causing the main clutch to Since the pressure plate cannot move sufficiently, even if the operating member is operated, the clutch will remain in a half-clutch state and there is a risk of burning out the clutch disc.

For this reason, the clutch adjustment interval becomes short.

In addition, although the latter allows for longer clutch adjustment intervals, it cannot absorb vibrations in the axial direction of the Rondo against vibrations of the main clutch caused by engine vibrations, so the operating member may move in the operating direction (vertical direction). , force may be applied to the clutch release lever.

For this reason, if the operating member moves, the driver's sense of operation will be incorrect, and if force is applied to the clutch release lever, the pressure plate will move, resulting in a half-clutch state, which will burn out the clutch disc and shorten the life of the release bearing. It becomes dark.

The present invention was devised in view of the above circumstances, and its purpose is to provide a main clutch operating device that prevents clutch vibration from propagating to the clutch release lever operating member and that allows for longer clutch adjustment intervals. It is.

Embodiments of the present invention will be described below with reference to the drawings.

An engine 1 is mounted on a vehicle body 2 via an elastic body 3, and a main clutch 4 is attached to the rear end of the engine 1.

As shown in FIG. 2, the main clutch 4 includes a base body 6 interlocked with an engine output shaft 5, an output shaft 7 rotatably provided on the base body 6, a clutch disc 8, and a pressure plate 9.
The clutch release lever 10 is composed of a clutch release lever 10 and an actuating member 12 having a hydraulic booster 11, and the clutch is released by actuating a lever 13 of the actuating member 12, which is conventionally known.

14 is an operating member (hereinafter referred to as a pedal) provided on the vehicle body side, and the pedal 14 is attached to a bracket 30 fixed to the vehicle body side (side frame 24) via a support shaft 15 so as to be vertically movable. The shaft 15 is linked via a lever 16 and a rod 17 to an intermediate lever 18 that is vertically movable.

A first linking rod 12 is provided on the intermediate lever 18, a second linking rod 20 is attached to the first linking rod 19 via a ball joint 21, and the second linking rod 20 is attached to the main clutch 4 with a support shaft. It is connected via a ball joint 25 to an operating lever 23 which is rotatably provided via a ball joint 22 .

The operating lever 23 is biased to rotate clockwise and is positioned in contact with a stopper bolt 27 provided on a bracket 26.

Reference numeral 28 denotes a tension spring provided on the lever 16 and the vehicle body side, and when in the neutral state, the pedal 14 is rotated upward and the stopper 29 is urged.
It is positioned in contact with the

Therefore, the first linking rod 19 and the second linking rod 20 are bent into a dogleg shape around the ball joint 21 when the pedal 14 is in the neutral position.

Next, the operation will be explained.

When the pedal 14 is depressed and rotated downward, the first linking rod 19 is pulled upward via the support shaft 15, lever 16, rod 17, and intermediate lever 18, and the first linking rod 19 and second linking rod 20 are After becoming straight, the operating lever 23 is rotated in the direction of the arrow.

When the operating lever 23 rotates in the direction of the arrow, the support shaft 22 and the lever 1
3, the booster 11 is actuated, and the clutch release lever 7 is swung to disengage the clutch.

31 is a stopper. Also, when the clutch is in the neutral position, the engine 1 vibrates against the vehicle body 2, causing the clutch 4 to move up.
When the engine 1 vibrates downward, left, right, forward, and backward, the first and second linking rods 19 and 20 bend further using the ball joint 21 as a fulcrum, or return to a straight state, thereby reducing the vibration of the engine 1. Therefore, no matter how the clutch 4 vibrates, the pedal 14 does not move up or down, and no force is applied to the clutch release lever 10.

Therefore, the driver's sense of driving will not be confused, the clutch disc 8 will not burn out, and the life of the bearing 10' of the clutch release lever 10 will not be shortened.

Furthermore, since the pedal 14 and the operating lever 23 are linked together, the adjustment interval can be made longer.

Since the present invention is configured as described above, when the operating member 14 is in the neutral position, the first and second linking rods 19 and 20 are vertically doglegged, so that the main clutch 4 is moved against the vehicle body 2. The intermediate lever 18 and the operating lever 23 are elastically displaced.
When the vertical mounting distance between the intermediate lever 18 and the intermediate lever 18 changes, the first and second linking rods 19 and 20 simply bend around the ball joint 21, and the intermediate lever 18 does not move vertically.

Therefore, the vibration of the main clutch is not propagated to the operating member 14 provided on the vehicle body 2 that operates the clutch release lever 10, which may cause burnout of the clutch disc, shorten the bearing life of the clutch release lever, or reduce the driver's sense of operation. This prevents the user from making a mistake, and also allows the clutch adjustment interval to be lengthened.
